SHOVELING AND LOADING MACHINE.

Application filed April 11, 1925. Serial No. 22,243.

To all whom t may concern.'

Be it known that I, HAROLD I. STAGE, a citizen of the United States, and a resident of San Francisco, county of San Francisco, State of California, have invented a certain Shoveling and Loading Machine, of which the following is a specification accompanied by drawings. 4

This invention relates to shoveling and loading apparatus and more particularly to that type of shoveling machine which is adapted to handle large quantities of material iii places where comparatively little head room is provided. Y

An objectw of the invention is to hold the shovel and to carry it back to its dumping position by means of a mechanism requiring comparatively little power tooperate and which, in carrying the shovel back to its dumping position, keeps the shovel relatively low.

Another object of the invention is to construct such a machine simply, cheaply and with few controls so thatit may be easily operated.

Other objects and advantages ofthis in vention will be iii part obvious and in part pointed out hereinafter.

Accordingly, the invention consists iii the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, the scope of the application of which will be indicated in the appended claims.

The drawing illustrates one form which the invention may assume in practice and includes,

Figure l, a vertical longitudinal section through the machine showing the internal arrangement of parts for operating the tions being broken away to more clearly show the cooperation of parts; and

Figure 3 is a side elevation of the machine showing more particularly the adjustability of the machine as to its height.

Referring to the drawings the machine includes a recipi'ocatory frame A upon which are mounted side chains B for supporting and carrying av shovel C from a shoveling position on the forward end of the .machine as shown in Figure l to a rearward position at which the shovel C is adapted to, dump material into a suitable mine car D or other receptacle. y

The chains B pass around rear sprockets E and front sprockets `F and are guided intermediate the sprockets by `iianges Cr which may be formed integrally with housings H inclosing the chains and sprockets at the sides, Figure 3. The housings H also maintain proper spacing between the shaft J supporting the rear sprockets E and the shaft K supporting the front sprocket F.

" The shovel C is pivotally mounted on the chains B and to this end the shovel is provided with a pair of brackets L which are chain Bf The roller R, pivot O and the pin S are in alignment so` that on the straight run of the chain B they hold the shovel C Vagainst tilting in either direction. As the shovel C passes over the front sprocket F, it turns about the pivot O and the pins S at front end of the shovel rest on the shoes T. This brings the shovel C to a convenient position for loading.` When the shovel is broughtback to its dumping position,`th'e rollers R are adapted to follow guides U preferably formed integrally with the housings'H. This tilts the shovel C upwardly so that the pins S leave the shoes T, causing the material therein to slide out into the car D.

The chain B is operated by power applied to certain of the sprockets preferably the rear sprocket E and for other purposes any suitable type of power may be employed such as the flat piston air motor V mounted on a bracket W integral with the housings H. The motor V is provided with a drive shaft X having a worm Y meshing with a worm wheel Z on the shaft J. The shaft X and the worm wheel Z are preferably inclosed in a gear case b which also supports bearings c for` the shaft X. The motor V a high-sided car, ,as forinstance D v(Figure .Tothis'enda stationaryibracket It having'anarcuateslotjo is adapted to cooperate withblts p'iixed on the outside-of eaclrof thehousings H. Upon loosening the nut of theboltp theLrear-end of thehousings H i may beliftedloroscillated about the shaft 1K and there-after `clamped fat the desired heights by retightening the nuts of Ithe boltsp. y v

lIn addition to the movements of the shovel'C backward and forward between its loading and dumping positions, Athe shovel ,platfo'rmg resting on Ya base r. lThis means .comprises a cylinder s mounted on theplat- :form Q 4andprovided with. apiston t having lapistonI rod u attached .by means of a clamp "zftofthe aXle'Kof the forward sprocketsF.

'The sidebeams to' of the frame A form "guideways for vrollers rv mounted on the cylinder s. "Brackets'c are mounted onthe side beams wLto rigidly supportthehousings A suitablemotiveuid such as comipressed air may be employedto actuate'the lpiston 't and'to'this en d a three-way valve ,g/ is Y`adapted to control the admission'of :motive fiuid'vfrom 'the -supply,passage Vg into a passage .a leading tov` the rear end of the cylinde'r '8, ortafpassage .2 leading V`to the frontend ofthecylinder. The valve g/ is adaptedfto'connect 'only one of thesepassages -Sz'and2 withmotive fluid at any-.one time and when .one of'these` passages is open to Vthe lfluid supply,V theother isjopen to eX vhaust through the passagel 3 leading to atl mosphere. p 'hand operated lever 4 is provided extending v.at the side of the machine:preferablyad- For controlling'the valve 'Ya jacent thelever igure 3) `for the convenience of' the' operator. y

Theplat'formg is adapted to swing abo-ut a rearwardpivot' so as to change the direction in whichthe:shovelpoints in itslposition for. loading' without` substantial change in its' dumping position. An arcuate 4plate 6 formedintegrallylwith theplatform g and adapted to pivot about 'the pin 5 isadapted to slideon Arollers :Tm'oun'ted on the-base fr having a similarly arcuate portion 8 beneath theplate l6. Meansfor swinging the platform g is provided by a rack 9 on the portion 8 and a pinion 10 on the plate 6. The pinion 10 is manually operated by a handle 1'1 on a shaft 12 provided with a bevel pinion '18 meshing with a bevel gear 14 on the shaft'lllto .which thepinion '.10 is attached. 'The.'bearingsldand '17 of the-shaft 12 are mounted on the cylinder s and the shaft 12 is A`adapted'to ext-end out to the side of the machine preferably near the levers and 4 :for the convenience" of the operator.

rlhe base 1 may be of any convenient form, If desiredfitkmay rest on wheels on thenrails 18 or,V as shown .in .the drawing, "may be arranged to slide thereon. "In .order '.to clamp the base 1"' inpositionythere is yprovided a bar 19 supporting the base r at the pivot 5 andextending across v the rails '18. At one end ofthe bar 19there 'areprovided two clamping jaws 20 which, when'the bar is turnedabout the pivot 5, are adapted to clamp oney ofthe railsl18 at. its bead. .If the base 'B were "forced backwardly7 its tendency is .to turn'the bar 19 stillfarther to clamp the'latter more firmly .on the rail. At the forward end ofthe 'base rthere are provided teeth 21 which-are disposed between 'thelrails A1`8'and project downwardly so as to engage one of the yties 22 upon which the rails"18 arefsupported.V The 'base 11 is triangular in shapeandxtherefore provides a three-point suspensionfor the machineresting directlyfon the rails at the forwardend ,fand at the pivot 5 onthe bar19 atthe rear. lrregularitiesin vthe'laying of the rails 18 therefore do not affect'the stability ofthe machine.
